我之前看有人说区别在于位置管理器，查阅资料后发现主要在于28379多支持了绝对式编码器的片上解码，这个是因为有CLB的原因吗？
如果是因为CLB，那么官方给出的文档中28377也同样有CLB，为什么它不支持绝对式编码器的片上解码呢？
以及，F28377D和28379D还有其它区别吗？
谢谢！

请您看一下下面帖子的回复
An exception will be the PARTIDH register, which is a read-only register with a value indicating the device (see datasheet). This will be different between F28377D and F28379D. If your software reads this register for some reason, you will need to make accommodation for this difference. Also, the flash API algorithms (used to do in-field flash upgrades) read this register to make sure the device is what it is supposed to be. You would not be able to build your code with the APIs resident in memory. They would need to be streamed in at re-programming time. If you aren't doing flash upgrade stuff, no need to worry about this.
